When I saved Caleb I was with Bernard, I didn't fight the alpha werewolf and increasing your libido shouldn't be possible during fights unless the enemy is unteasable. Your comment confuses me, because contraddicts what I've always done, and makes me worry that my guide is too much incomplete since my comment wasn't usefull to you. If you confirm that that is what you've done, I'll try to replay this part like you did, so I can update the guide. Sorry for my disbelief, I didn't know what you did was possible. XD
